Yeah. That's extruded inner glow, which has a very plastic look to it.

It's pretty cool.

So, has this script been updated? I can't keep up.

Yes, the script has been updated to support gradient shadows. You can grab it from Gimp Scripts.

I tried it with a vase.

It fits well with the colors of the vase. It looks like you cropped off the shadow a little at the bottom.

Actually I used a wood grain vase and did the gc shadows around it, then deleted the vase and just left the outline. I selected the outline then ran the filter again. The reason the shadow is cropped is because I unchecked the resizing. When I don't do that, my whole image shrinks, is there a way around that?

Resizing doesn't change the size of the image. It resizes the canvas to allow room for the shadow, if your shadow offsets extend past the current canvas. You can manually resize the canvas to allow room for the new shadow, but the script will do it for you automatically when you leave the resize toggle checked.

Thank you, AGAIN. Is this better?

Yes. I think it looks nice, Molly.

The edges on the vase are a bit ragged but maybe a small blur may help that.

GC Shadow has been updated to Version 1.2 to correct a bug where it was not properly handling a linked layer.

You can grab the update from here.

Got it, thanks
